IwIACHIIIE FOR VJINDING VTARP SHEETS.

Application filed February 5, 1925. Serial No. 6,978.

To all whom it may concern:

Be it known that I, EDWI E. Garrison, a citizen of the .United States,residing at Chester, in the county of Delaware and State ofPennsylvania, have invented certain new and useful Improvements inMachines for Winding Warp Sheets, of which the following is aspecification.

My invention relates to winding machines and is primarily designed forwinding a binder thread upon the warp sheets which pass through thesolutions employed for mereerizing yarns.

In mercerizing yarns, strands of yarn have usually been grouped in rope"form and a number of groups are concurrently led through themercerizing solutions. A bind ing thread is wound spirally about eachgroup to hold loose ends of threads which may be broken in themercerizing process to their group and prevent their clinging to andbeing wound around the rollers in the mercerizing mechanism. Thisrequires a winding unit for each group. It is common practice to providemechanism capable of dealing with 24 groups at one operation and thisinvolves providing 24 winding units. It has recently been foundadvantageous to group the strands slde by side 1n single ply, therebyforming a s ngle warp sheet, and to bind the entire warp sheet with asingle thread instead of binding each group separately.

The object of this invention is to provide a machine for winding, orunwinding, warp sheets or other continuous sheets which may require suchwinding or unwinding.

I have illustrated my invention in con nection with asingle ply warpsheet but it is adapted for use with continuous sheets of any type. I i

In the -drawings,

Figure 1 is a topplan view,

Figure 2 a side'elevation,

Figure 3 a section on line 33 of Figure 2,

Figure 4 a section on line H of Figure .2,

Figure 5 a vertical section through one form of spool carrier and spool,

Figure 6 an enlarged detail of a thread guide, and

Figure 7a side elevation of another form of spool with the thread guide.

In the drawings, 1 indicates the frame of the machine, 2 the top ortable, 3 cross bars, 1 a guide slot in the table through which the warpis led, 5 an oblong raceway of slot type encompassing the warp andhaving guide walls 6 and 7 within and upon which a spool-carrier 8travels, 9 a drive sprocket and 10 a companion sprocket both disposedbeneath the raceway, 11 a sprocket chain carried by the sprockets,encompassing the warp and having one of its links 12 d etachablyconnected with a bearing block 13 adapted to support a spool-carryingspindle 14, 15 a sprocket chain spaced from chain 11, disposed parallelthereto and in the same horizontal plane therewith and detachably fixedto a series of brackets 16 extending from the frame, 17 a sprocket wheelfixed to the spool spindle and meshing with chain 15, and 18 the spoolwhich carries the binding thread 19. The spool is rotatable upon itsspindle 14 and is mounted upon spool-carrier 8. The spool-carrier, shownin detail in Figure 5, preferably consists of a sleeve 20 having anannular flange 21 and an enlarged part 22 and is threaded at its upperend to receive a stepped ball bearing 23 having annular flanges 2A and25. The upper flange .25 carries a friction disk 26 upon which spool 18is seated. The lower flange supports the carrier upon the guide walls 6and 7 .of the raceway and flange 21 holds the carrier against upwarddisplacement. Enlarged part 22 fits in the raceway slot and serves as aguide block for the spool carrier. As the spool is seated upon frictiondisk 26, it is free to yield to any unusual strains. A bracket 27,extending from the spool carrier, carries a standard 28 upon which athread guide 29 is adjustably mounted. The thread guide has twofiXedmembers or eyes 30 and 31 extending therefrom and adapted to receive thebinding thread 19. A shaft 32 is rockably mounted in the guide andcarries, a crank arm 33 which carries, at its free end, an electricalcontact member 34-, adapted to engage with a fixed contact member 35extending from the guide, the Com tact member being in a normally opencircuit including a switch which controls the motor. The guide isprovided, between the stems of eyes 30 and 31 with a socket 36 and ablock 37 fixed to shaft 32 is rockably seated in the socket. A pin 38extends from the block in a plane between eyes 30 and 31. The bindingthread 19 as it goes from the spool to the warp sheet passes through theeyes and over pin 38. The tension of the thread normally holds the crankarm in raised position and contact member 34 out of contact but, if thethread should break or the tension cease for any cause, the weight ofthe crank arm causes it to drop and close the circuit. Brushes 39 and 40are mounted upon the spool carrier and are connected by wires 41 and 42with contact members 34 and 35 on the thread guide. The brushes areadapted to respectively engage conducting strips 43 and 43 mounted uponinsulating brackets 44 extending from the frame. Strips 4-3 and 48 arein circuit through a source of current 4;?) with a solenoid switch 46which controls the motor 47 and engagement of contact members 34: andcloses the circuit through the solenoid switch and stops the motor. 7

Drive sprocket 9 is mounted upon a shaft 48. A drive shaft 49 carries aspiral pinion 50 which meshes with a spiral gearbl on shaft 18 andimparts motion to the shaft and consequently to the drive sprocket andthe movable chain.

- The thread spool shown in Figures 2, 3 and 5 is in the form of acylinder. In Figure 7 I have shown a cone-shaped spool 23 which ismountedin the same way as spool 23 but the'standard 28 is extended andthe thread guide 29 is disposed above instead of alongside the spool.

In operation, the binding thread which I has been wound upon the spool,leads from the spool through eye 30, over pin 38 and through eye 31 tothe warp sheet. Motion being imparted to drive sprocket 9 from driveshaft 49, sprocket chain 11, to which spool carrier 8 is connected, iscaused to travel continuously around the warp sheet thereby causing thespool carrier to travel in raceway 5 around the warp sheet. As the spooland thread guide are mounted upon the spool carrier, they also travelaround the warp sheet and cause the thread to be wound spirally thereon.As the spool travels rotary motion is imparted to its spindle lt bysprocket wheel 17 meshing with fixed chain 15. As the spool is seatedupon friction disk 26 which is carried by a ball bearing member it isfree to yield to undue strains. In case the binding thread should break,crank arm 33, which has been held in raised position by the tension ofthe binding thread upon pin 38, will drop by gravity thereby bringingcontacts 34 and 35 into engagement and closing the circuit throughsolenoid switch 46 and thereby stopping the motor.

While I have described my invention as taking a particular form, it willbe understood that the various parts may be changed without departingfrom the spirit thereof. and hence Ido not limit myself to the preciseconstruction set forth, but consider that I am at liberty to make suchchanges and alterations as fairly come within the scope of the appendedclaims.
